provide novel means for reciprocating the,

cooperating blades of a cutter bar to insure the operation thereof.

A further object of the invention is to provide a structure of this character whichV will not interfere with the movement of the cutter bar into and out of operation.

A still further object of the invention is the provision of a novel form of cutter bar which will not increase the weight of the machine nor increase the draft on the animals or Vmachine employed for moving the device supplied with my cutter bar.

view which will appear as the description proceeds, the invention resides in the com'- bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, Without departingfrom the spirit of the invention.

Referring to the drawings z- Figure 1 is a fragmental plan view of a cutter bar constructed in accordance with the present invention.

Figure 2 is a sectional view taken on line 24-2 of Figure 1.

Figure 3 is a. sectional view taken on line 3-8 of Figure 1, parts thereof being removed. Y l

Figure 4: is a detail view ofthe connecting the cutter' bars.

Figure 5 is a sectional view through the connecting block and connecting lever, taken on line 5 5 of Fig. l.

Figure 6 is a perspective viewof the pivot pin for the connecting lever; and

Figure 7 is a perspective view of the connecting block.

With the foregoing and other objects inv Referring tothe drawings in detail, the reference character 5 designates the base or supporting head of the cutter bar which is provided with upwardly extending arms 6 having openings by means of which the cutter bar may be connected to the frame of a harvester, to permit Vthe cutter bar to be raised and lowered at the will of the operator.v

As shown by Figure 1 of the drawings, the arms 6 have connection with the pin 7 that extends through suitable openings in the bracket 8 of the harvester, there being provided means for securing the pins 7 within the bracket 8.

The base 5 is cut away as at 9 to receive the plate 10 which carries the pivot pin 11 that is secured thereto as by means of the yrivets 11', the pivot pin 11 is of a length to extend to a point flush with the upper edge of the base to accommodate the connecting lever 12, which pivots thereon.

The cutting element includes a pair of reciprocating bars 13 and 14 respectively, each bar carrying a plurality of blades 15 that have beveled edges forming cuttin surfaces so that material which falls be tween adj acent blades will be readily cut by the reciprocating blades.

As shown, the bar 13 is secured to plate 23 to be hereinafter more fully described.

The bloclr 13 Vis secured to the under side of the plate 23 and has a cutout portion to embrace one of the enlargements forming one end of the connecting lever 12, whereby movement of the bar 13 produces a pivotal movement of the connecting lever 12, moving one end of the connecting lever in one direction, while the opposite end thereof is moved in the opposite direction.

The cutter bar 14 has connection with the connecting lever 12 as through the block 16 which is cut away to embrace the head 17 formed at one end of the lever 12, so that the head will move within the cut out portion and accomplish the reciprocation of the cutter bar 111.

Bolted to the base 5, are the brackets 22 which provide guides for the plate 23 to which bar 13 is connected. Thus it will be seen that movement of the plate 23 produces a relative movement of the cutter bars. `A ball 18 is formed on the upper surface of the plate 23, and this ball forms one section of tlie ballA and socket. joint which connectsitliey plate and tlre operting arni 19l` that` has" a socket member 2O formed at one end` thereof, which socket member grasps the ball1`8.

This arm 19 llas its opposite end connected to an eccentric, and by means of Which-reciprocating motion is imparted to the operating arm 19 which in turn-impartsV reciprocating motion to` tli'el cutterbars" 1--3 and' 14.V It might be further stated that guurdlingers 21. zire associated Witlr tlie cutter bl'i'uiles, and through these g-'L'rardV fingers the cutter blades operate', tliegird Having thus" clescribecl' theI invention,t
